Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Before explaining the frame structure provided by the embodiment of the present application, an application scenario of the frame structure provided by the embodiment of the present application is specifically explained: referring to fig. 1, a schematic diagram of a vehicle frame structure in the related art is shown, as shown in fig. 1, the vehicle frame structure includes a front subframe, a front longitudinal beam 20, a front impact beam assembly 30 and a front wheel house side beam assembly 40, the front subframe is mounted at a first position of the front longitudinal beam 20 through a front subframe mounting plate assembly 101, the front impact beam assembly 30 is connected with a front impact beam connecting plate assembly 302, the front impact beam connecting plate assembly 302 is connected with a front impact beam mounting plate assembly 301, the front impact beam mounting plate assembly 301 is mounted at an end portion of the front longitudinal beam 20, a front pillar 41 is connected to the front longitudinal beam 20, the front pillar 41 is connected with a headlamp mounting plate 42, the headlamp mounting plate 42 is connected at a first end of the front wheel house side beam assembly 40, a second end of the front wheel house side beam assembly 40 is connected at a second position of the front longitudinal beam 20, and the first position is different from the second position.

In the event of a vehicle collision, i.e., when the front impact beam assembly 30 of the vehicle is impacted, the front impact beam assembly 30 transmits the impact force to the front side frame 20, and then the front side frame 20 transmits the impact force to the front sub frame mounting plate assembly 101, and then to the front sub frame through the front sub frame mounting plate assembly 101, and the impact force of the front side frame 20 is transmitted to the second end of the front wheel house side beam assembly 40. In the process of the transmission of the collision force, the collision force is firstly transmitted to the front longitudinal beam 20, and then is transmitted to the front subframe and the front wheel cover side beam assembly 40 through the front longitudinal beam 20, so that the collision force is not synchronous when being transmitted on the front longitudinal beam 20, the front subframe and the front wheel cover side beam assembly 40, the influence is caused on the frame structure, the frame structure is easy to lose stability, and the stability of the frame structure is poor.

Referring to fig. 2, a schematic view of a vehicle frame structure provided by an embodiment of the present application is shown, referring to fig. 3, a front view of a vehicle frame structure provided by an embodiment of the present application is shown, referring to fig. 4, a cross-sectional view at a-a in fig. 3 is shown, referring to fig. 5, an axial view of a mounting assembly provided by an embodiment of the present application is shown, referring to fig. 6, a front view of a mounting assembly provided by an embodiment of the present application is shown, referring to fig. 7, a bottom view of a mounting assembly provided by an embodiment of the present application is shown, referring to fig. 8, a top view of a mounting assembly provided by an embodiment of the present application is shown, referring to fig. 9, one axial view of a front side rail provided by an embodiment of the present application is shown mounted to the mounting assembly, and referring to fig. 10, a second axial view of a front side rail provided by an embodiment of the present application is shown mounted to the mounting assembly. The frame structure is applied to a vehicle, and as shown in fig. 2 to 10, the frame structure includes: a front subframe 10, a front side member 20, a front impact beam assembly 30, a front wheel house side beam assembly 40, and a mounting member 50.

The mounting assembly 50 includes a mounting wall 501, a mounting cavity 502, a first mounting portion 503 and a second mounting portion 504, the first mounting portion 503 and the second mounting portion 504 are both connected to a first surface of the mounting wall 501, and the mounting cavity 502 is located between the first mounting portion 503 and the second mounting portion 504. The front side member 20 is partially mounted in the mounting cavity 502, the front wheel house side member assembly 40 is mounted on the first mounting portion 503, the front subframe 10 is mounted on the second mounting portion 504, and the front wheel house side member assembly 40 is connected to a second surface of the mounting wall 501, the second surface being opposite to the first surface.

In the embodiment of the present application, the mounting component 50 includes a mounting wall 501, a mounting cavity 502, a first mounting portion 503 and a second mounting portion 504, so that the front side member 20 can be partially mounted in the mounting cavity 502, the front wheel house side member assembly 40 can be mounted in the first mounting portion 503, the front subframe 10 can be mounted in the second mounting portion 504, and the front wheel house side member assembly 40 can be connected to the second surface of the mounting wall 501. Since the first mounting portion 503 and the second mounting portion 504 are connected to the first surface of the mounting wall 501, the front side frame 20, the front wheel house side rail assembly 40, the front sub frame 10 and the front impact beam are connected together by the mounting component 50, so that the front impact beam can transmit the impact force to the first surface of the mounting wall 501 when the vehicle is collided, that is, the front impact beam is collided, the first surface of the mounting wall 501 simultaneously transmits the impact force to the mounting cavity 502, the first mounting portion 503 and the second mounting portion 504, that is, the mounting wall 501 transmits the impact force to the front side frame 20, the front sub frame 10 and the front wheel house side rail assembly 40, respectively, so that the impact force can be transmitted to the front side frame 20, the front sub frame 10 and the front wheel house side rail assembly 40 simultaneously, thereby the front side frame 20, the front sub frame 10 and the front wheel house side rail assembly 40 can simultaneously decompose the impact force, the problem that the stability of the frame structure is lost due to asynchronous transmission of collision force is solved. That is, in the embodiment of the present application, the front subframe 10, the front side frame 20, the front wheel house side beam assembly 40 and the front impact beam are connected together through the mounting component 50, so that when the front side frame 20 collides, the collision force can be synchronously transmitted to the front side frame 20, the front subframe 10 and the front wheel house side beam assembly 40 through the mounting component 50, so that the front side frame 20, the front subframe 10 and the front wheel house side beam assembly 40 can simultaneously decompose the collision force, thereby avoiding the occurrence of the problem that the frame structure loses stability due to the asynchronous transmission of the collision force, and further improving the stability of the frame structure.

In addition, in the related art, as shown in fig. 1, the front impact beam assembly 30 is connected to the front impact beam connecting plate assembly 302, the front impact beam connecting plate assembly 302 is connected to the front impact beam mounting plate assembly 301, and the front impact beam mounting plate assembly 301 is mounted at the end of the front longitudinal beam 20, so that the front impact beam assembly 30 and the front longitudinal beam 20 need to be connected by the front impact beam connecting plate assembly 302 and the front impact beam connecting assembly, which results in poor assembly precision when the front impact beam assembly 30 and the front longitudinal beam 20 are connected.

In the embodiment of the present application, the front longitudinal beam 20 is mounted in the mounting cavity 502 of the mounting component 50, and the front impact beam assembly 30 is connected to the mounting wall 501 of the mounting component 50, so that the connection between the front longitudinal beam 20 and the front impact beam is simplified, and the assembly precision is high when the front longitudinal beam 20 and the front impact beam assembly 30 are connected.

In addition, when the vehicle collides at a low speed, it is required that the front side frame 20 of the vehicle cannot deform, and therefore, in the related art, as shown in fig. 1, the front side frame 20 is generally contracted toward the rear of the vehicle, that is, a joint of the front side frame 20 and the front impact beam is contracted toward the rear of the vehicle, so that a distance between the joint of the front side frame 20 and the front impact beam and a collision position of the front side frame 20 is relatively large, and thus, when the front impact beam collides, the front impact beam has a relatively long impact-absorbing distance, and thus, the deformation of the front side frame 20 is avoided. However, since the front subframe 10 is mounted on the front longitudinal beam 20 through the front subframe 10 mounting plate assembly, and the front subframe 10 mounting plate assembly is far away from the front impact beam assembly, when the joint of the front longitudinal beam 20 and the front impact beam contracts towards the rear of the vehicle, the front subframe 10 mounting plate assembly also contracts towards the rear of the vehicle, so that the dynamic stiffness of the front subframe 10 and the front subframe 10 mounting plate assembly in the X direction of the vehicle is poor after the front subframe 10 is connected with the front subframe 10 mounting plate assembly. The X direction of the vehicle refers to a direction from the front to the rear of the vehicle or a direction from the rear to the front. Dynamic stiffness refers to the ability to resist deformation under dynamic loads.

In the embodiment of the present invention, the front impact beam assembly 30 is connected to the mounting wall 501 of the mounting component 50, the front longitudinal beam 20 is partially mounted in the mounting cavity 502, the front wheel house side beam assembly 40 is mounted in the first mounting portion 503, and the front subframe 10 is mounted in the second mounting portion 504, so that when the front impact beam assembly 30 collides, the collision force can be simultaneously resolved by the front longitudinal beam 20, the front subframe 10, and the front wheel house side beam assembly 40, which not only can avoid the problem of deformation of the front longitudinal beam 20 when the collision occurs at low speed, but also can prevent the front longitudinal beam 20 from shrinking backward, thereby improving the dynamic stiffness of the front wheel house side beam assembly 40 in the X direction of the vehicle.

Additionally, in some embodiments, as shown in fig. 5, the mounting assembly 50 may further include a first sidewall 505, a second sidewall 506, a first support wall 507, and a second support wall 508. The mounting wall 501 is provided with a through hole, the first side wall 505, the second side wall 506, the first support wall 507 and the second support wall 508 are arranged on a first surface of the mounting wall 501, the first side wall 505, the second side wall 506, the first support wall 507 and the second support wall 508 are all located in an aperture of the through hole, the first side wall 505, the second side wall 506, the first support wall 507 and the second support wall 508 enclose a containing cavity, the containing cavity is communicated with the through hole, the first side wall 505 is opposite to the second side wall 506, the first support wall 507 is opposite to the second support wall 508, and the containing cavity and the through hole form the mounting cavity 502. The first mounting portion 503 is connected to the first surface of the mounting wall 501 via a first support wall 507, and the second mounting portion 504 is connected to the first surface of the mounting wall 501 via a second support wall 508.

Since the mounting wall 501 of the mounting assembly 50 is provided with a through hole, the first side wall 505, the second side wall 506, the first supporting wall 507 and the second supporting wall 508 are all disposed on the first surface of the mounting wall 501, and the first side wall 505, the second side wall 506, the first supporting wall 507 and the second supporting wall 508 are all located at the opening of the through hole, the first side wall 505, the second side wall 506, the first supporting wall 507 and the second supporting wall 508 can enclose a receiving cavity, and the receiving cavity is communicated with the through hole. In addition, since the first side wall 505 is opposite to the second side wall 506, and the first support wall 507 is opposite to the second support wall 508, the longitudinal section of the accommodating chamber may be quadrilateral. And the longitudinal section of the front longitudinal beam 20 is generally quadrilateral, so that when the longitudinal section of the accommodating cavity is quadrilateral, the outer peripheral surface of the front longitudinal beam 20 can be supported by the cavity wall of the accommodating cavity after the front longitudinal beam 20 is partially embedded into the accommodating cavity, so that the front longitudinal beam 20 can be well limited in the accommodating cavity, and the front longitudinal beam 20 is prevented from moving along the circumferential direction of the front longitudinal beam 20. In addition, when the longitudinal section of the accommodating cavity is quadrilateral, the front longitudinal beam 20 can be conveniently embedded into the accommodating cavity. In addition, when the first mounting portion 503 is connected to the first surface of the mounting wall 501 through the first supporting wall 507 and the second mounting portion 504 is mounted to the first surface of the mounting wall 501 through the second supporting wall 508, the first mounting portion 503 and the second mounting portion 504 can be connected to the mounting wall 501 conveniently, that is, the first mounting portion 503 can be directly mounted on the first supporting wall 507, the second mounting portion 504 can be directly mounted on the second supporting wall 508, so that the first mounting portion 503 is connected to the mounting wall 501, and the second mounting portion 504 is connected to the mounting wall 501.

That is, when the front mounting assembly 50 includes the first side wall 505, the second side wall 506, the first support wall 507 and the second support wall 508, and the first side wall 505, the second side wall 506, the first support wall 507 and the second support wall 508 enclose a receiving cavity at the opening of the through hole of the mounting wall 501, it can be convenient for the front longitudinal beam 20 to be embedded into the receiving cavity, and the cavity wall of the receiving cavity can limit the front longitudinal beam 20. Further, by providing the first support wall 507 and the second support wall 508, it is also possible to facilitate the connection of the first mounting portion 503 and the second mounting portion 504 to the mounting wall 501.

Here, the longitudinal section of the accommodation chamber refers to a section in a direction perpendicular to the extending direction of the front side member 20. The longitudinal section of the front side member 20 refers to a section in a direction perpendicular to the extending direction of the front side member 20.

It should be noted that, in the embodiment of the present application, the shape of the through hole in the mounting wall 501 is the same as the shape of the longitudinal section of the accommodating cavity, that is, the shape of the through hole in the mounting wall 501 is a square. In addition, the area of the through hole is equal to the area of the longitudinal section of the accommodating cavity.

In addition, in the embodiment of the present application, the manner of mounting the front side member 20 to the receiving cavity may be: a plurality of through holes are respectively formed in the first side wall 505 and the second side wall 506, a plurality of threaded holes are formed in the front longitudinal beam 20, after the front longitudinal beam 20 is partially embedded into the accommodating cavity, the plurality of threaded holes in the front longitudinal beam 20 respectively correspond to the through holes in the first side wall 505 and the through holes in the second side wall 506, and then a bolt penetrates through one through hole to be embedded into one threaded hole, namely, the front longitudinal beam 20 is partially installed in the accommodating cavity through the bolt. In addition, the front side member 20 may be partially installed in the accommodating cavity by riveting, that is, a plurality of through holes are provided in each of the first side wall 505 and the second side wall 506, a plurality of rivet holes are provided in the front side member 20, and one rivet is inserted into one rivet hole through one through hole. Of course, the front longitudinal beam 20 can be partially installed in the accommodating cavity in other manners, such as clamping, and the embodiment of the present application is not limited herein.

In the embodiment of the present invention, when the material of the front side member 20 is different, the process before the front side member 20 is attached to the accommodating chamber is also different. When the material of current longeron 20 was the steel, perhaps the metal material of easy corruption, at this moment, need coat the structure glue on front longitudinal 20 for front longitudinal 20 installs when holding the chamber, and front longitudinal 20 with hold between the chamber insulating, avoid front longitudinal 20 and hold and produce electrochemical reaction between the chamber, influence front longitudinal 20 and hold being connected between the chamber. When the material of front longitudinal beam 20 was the aluminum alloy, perhaps indelible corrosive metal material, at this moment, can directly install front longitudinal beam 20 in holding the chamber, need not to handle front longitudinal beam 20.
